I. Introduction
Over the past three and a half decades, China has seen a surge in the ratio of male to
female newborns. A biologically normal sex ratio at birth calls for around 105 or 106 boys for
every 100 girls (Sen, 1990), and before 1985, Chinese parents gave birth to about 107 newborn
boys for every 100 girls, a figure that falls within the normal range for sex ratio at birth. In the
years following the enactment of the One Child Policy, which dictated that most Chinese couples
only have one child or face steep fines and other legal penalties, this number has climbed
dramatically. Between 2005 and 2010, China’s sex ratio at birth averaged 117 boys for every 100
girls born– an alarmingly high figure. Economic incentives and cultural preferences favoring
boys, coupled with the constraints on childbearing opportunities imposed by the One Child Policy
have resulted in a startling reduction in the number of women in China today.
While the One Child Policy has had an undeniable negative impact on China’s deficit of
female babies, the significant reduction in the number of girls born in China since 1980 also owes
a great deal to the widespread adoption of ultrasound technology in China, which has given
prospective parents the tools necessary for determining the sex of an unborn child. Sex-selective
abortion accounts for an overwhelming majority of China’s excess males (Wei, Li, Hesketh, Liu,
and Zhang, 2005), and increased access to the requisite technology has significantly widened the
gap in the number of newborn boys and girls (Chen, Li, and Meng 2013).
Although the One Child Policy sounds as though it constitutes a highly rigid legal
framework with regard to fertility, it is a much less dictatorial policy than its name suggests. In an effort to reduce high male birthrates and to appease groups who are especially resistant to fertility policy, China’s national government, as well as provincial and municipal authorities, has 4 instituted a number of exceptions to the One Child Policy, allowing certain parents to have additional children, though these efforts have met with little success. These exceptions most frequently apply to poor, rural families, who exhibit high rates of son preference relative to the rest of China’s population. Often, rural families are allowed to have a second child provided that they have already had a daughter. Furthermore, financial disincentives for additional fertility create an environment where well-off families are more likely to be able to afford additional children. Since selecting for the sex of an unborn child may require bribery or expensive procedures such as sperm-sorting, wealthy families are better situated to engage in sex-selection.
Thus, second children in China are even more disproportionately male than their older siblings, with 62% of births following a daughter being male in 2000 (Ebenstein, 2010: 92).
This paper examines the determinants of China’s increasingly unbalanced sex ratio at birth with a special focus on maternal educational attainment. First, I provide a brief summary of the One Child Policy, focusing on some particulars of its implementation and justification. I then give a brief survey of economic and demographic literature relating to the effects and determinants of sex-selective behavior in developing countries, especially in China. A theoretical discussion of education and son preference follows, including an outline of a model of the effect of education on sex-selective behavior in India and a model of fertility decision making in the context of the One Child Policy. Since India and China are similar in both their levels of development and degrees of son preference, the first of these models offers useful perspective on the mechanics of son preference in developing countries in general. The second of these models focuses more on the decisions of individuals in the context of the One Child Policy, though it does not detail the effects of education on these decisions. 5
This paper attempts to reconcile the conclusions of these two models through empirical
analysis, demonstrating a positive correlation between maternal education and son preference in
Chinese families following the institution of the One Child Policy. In spite of the restrictive policy environment fostered by the One Child Policy, women have a great deal of agency in decisions regarding their own fertility, and educational attainment is one of the primary determinants of how these decisions are made. This indicates that the One Child Policy effected a shift in the factors influencing Chinese parents with regard to sex-selection, as education has become a significant predictor of son preference in Chinese individuals who have had children since 1980.
II. History of the One Child Policy
The Chinese Communist Party began its efforts to curb China’s unchecked population growth in the 1960s. After famine claimed nearly 30 million lives between 1959 and 1961, the fertility rate in China climbed to alarmingly high levels during the following decade. While the national government made no explicit restrictions on the number of children couples could have, it initiated a campaign to promote birth control in an effort to lower national fertility. This ended with the dawn of the Cultural Revolution in 1966, and the government ceased to manage fertility rates until 1970.
Chinese fertility policy in the 1970s took a similar tack to the short-lived attempts of the
1960s, though in a more coordinated fashion. Instead of dictating how many children couples could have, the government strongly encouraged parents to have no more than two children. In fact, reductions in China’s national fertility rate were more substantial in the 1970s than in any other decade, as the total fertility rate (TFR) fell from 5.8 to 2.2 (Liang, Lee: 2006: 14). Increased female participation in the labor force, and a number of acute shortages of food and other 6
essentials had undeniably significant impacts on the fertility rate during this period. Nonetheless,
as the 1980s began, China’s government took an even stronger stance against population growth.
The One Child Policy may be the most ambitious example of demographic engineering in
human history. Its official implementation in January of 1981 1 marks yet another turning point in the composition and growth of China’s population. Much of the theoretic justification for these measures stems from the resurgence of Malthusianism in the late 1960’s and early 1970’s. Works such as Limits to Growth (Meadows et al.: 1972) offered numeric justifications for their dire predictions about the consequences of unchecked population growth in the developing world
(Hartmann: 1995). As China turned its sights toward Zhou Enlai’s “Four Modernizations” 2 in the late 1970’s (at that point under the leadership of Deng Xiaoping), China’s high rate of population growth loomed as a major obstacle to its economic prosperity.
Justifications for the One Child Policy applied this “Malthusian orthodoxy” of early 1970’s control theory and applied it in broad, sweeping strokes. While politicians touted a number of numeric projections used to illustrate the severity of China’s population problems as unassailably correct, reliable demographic statistics were simply unavailable in China at that time
(Greenhalgh, 2003). In the absence of alternate research or projections, the One Child Policy appeared to be the only way to avert certain disaster.
Regardless of the reasoning behind it, the One Child Policy has brought about further reductions in the rate of population growth in China. Incidentally, its implementation coincides with one of the most remarkable periods of economic growth in any country in recorded history.
The natural growth rate of China’s population has fallen considerably in the period since 1980,
1 The first official documents authorizing the state to dictate fertility policy date to January 4, 1981, when they were drafted by China’s State Planning Commission (Vogel, 2011). However, the policy was first proposed in 1979 (Lee, Chang: 2006). 2 That is, agriculture, industry, national defense, and science and technology. 7
averaging a 2.7% annual reduction, while GDP growth has averaged 9.94% (UNData) in each year
over the same period.
While the One Child Policy may have had a substantial effect in the form of reductions in
the rate of population growth in China, it has also carried with it a number of much more
insidious demographic side effects. The rate of population growth in China has slowed a great
deal since the introduction of the One Child Policy, but the ratio of boys to girls born over that
same period has increased consistently and dramatically. The sex ratio at birth in China begins to
climb from a relatively normal level of 107 boys for every 100 girls born between 1980 and 1985
to a truly concerning level of 117 boys for every 100 girls born between 2005 and 2010
(UNData). By the year 2000, around 9 million baby girls were “missing” due to abnormally high rates of male births in the years since 1980 (Ebenstein, 2010). This trend continued into the new millennium unabated, as China’s sex ratio at birth has hovered around 120 boys for every 100 girls for the past decade and a half.
The necessity of the One Child Policy has also come under greater scrutiny in recent years.
Rapid economic growth in China since 1978 has also had an undeniable effect on birth rates, as rising national income and higher rates of female participation in the labor force have increased the opportunity cost of having a child for many parents. In fact, many countries that have followed a similar developmental path to that of China have experienced similar reductions in the rate of fertility in the years since 1980 (Wang, Cai: 2010).
While its name might indicate rigid uniformity in the fertility of Chinese families, the One
Child Policy admits a number of exceptions. For instance, couples who give birth to disabled
children or whose first child dies in infancy are often allowed to have a second child. Moreover,
families who live in especially poor, rural areas or who are engaged in labor-intensive 8
occupations (such as certain forms of agriculture) are often allowed to have additional children
as well. An exhaustive list of exceptions to the One Child Policy can be found in Gu et al. (2007).
The most widely invoked exception to the One Child Policy allows families with one
daughter to have a second child. This amendment to the Policy was introduced in many provinces
during the mid-1980s in an effort to combat China’s rising sex ratio at birth and to quell rural
resistance to the new policy. However, many parents who are subject to this exception have
opted to engage in sex-selective behavior for their second child, resulting in an extremely high sex ratio at birth among second-born children in China (Ebenstein: 2010).
While the One Child Policy owes its inception to the national government, mechanisms of
enforcement and exceptions vary considerably across polities and time. Implementation of the
policy has been a largely decentralized affair. Mechanisms of enforcement range from forced
sterilizations and abortions to financial penalties such as fines or wage cuts. During the 1990s, financial penalization became the primary means of dissuading parents from having further children, although reports of state-mandated abortion also continue to come out of China.
III. Literature Review and Data
There is a small but substantial body of demographic and economic literature dedicated to examining the causes of China’s unbalanced sex ratio at birth. A number of cultural and economic forces shape fertility decisions in China, and their effects may be difficult to examine separately
(Lipatov, 2008; Ebenstein 2011). Indeed, rates of sex-selection appear to be lower in areas where female income is relatively high (Qian, 2008). The One-Child policy has also resulted in higher rates of sex-selective abortion and lower survival rates for female infants (Arnold and Zhaoxiang,
1986; Zhu, Lu, and Hesketh, 2009), especially among second- or third-born children (Johansson 9
and Nygren, 1991). In fact, the One-Child policy could account for more than half of China’s excess
male births from 1991-2005 (Li, Yi, Zhang: 2011), though ultrasound technology has undoubtedly
also played a large role in China’s rising sex ratio at birth. Nonetheless, increasingly severe enforcement measures during the 1990’s may have caused parents to refrain from reporting
female births (Hull, 1990), a fact that introduces a sample selection problem to regressions on more recent census data (Goodkind, 2011).
China’s high ratio of boys to girls has grave social implications and consequences.
Countries with high numbers of males relative to females in their population as a whole may be more likely to experience high rates of violent and petty crime (Hudson and den Boer, 2004).
Furthermore, the harsh, institutionalized nature of China’s family planning policy compounds many of the issues that give rise to son preference in Chinese society. Such rigid, top-down enforcement of the One-Child policy may foster an environment where males dictate fertility decisions, increasing female vulnerability within the household and society (Chen, 2008). In addition to economic disincentives, Chinese officials have often enforced the One-Child policy
with outrageously coercive methods, as well as forced sterilizations and late-term abortions
(Hartmann, 1995).
In other Asian countries such as India, a few studies address the link between education
and sex ratio at birth. Additional years of maternal education appear to improve survival rates for
female children in India (Bourne and Walker, 1991). However, while further years of education
are correlated with lower degrees of son preference in individuals, which translates into lower
rates of sex-selection in more educated areas, the higher levels of economic opportunity that
accompany greater educational attainment make technology for sex-selection such as ultrasound 10 more readily available to prospective parents. 3 This suggests that areas with higher numbers of educated people may, paradoxically, have higher sex ratios at birth (Echavarri and Ezcurra,
2010). In fact, changes in female literacy do not necessarily presage improvements in the sex ratio at birth, and can even cause son preference to become more pronounced (Clark, 2000).
For the purposes of this paper, I have chosen to use individual-level data from the 2000
National Household Survey from China. The 2000 National Household Survey includes the most complete set of individual level data currently available from China. Individual level census data are also available from 1982 and 1990, but responses do not include a number of essential variables, including those correlated with income. Respondents in the 2000 census reported their highest level of educational attainment and whether or not they were literate, essential variables in my analysis. However, since these variables were self-reported, they may introduce some measurement error to any statistical analysis of the responses. Moreover, this census includes data on respondents’ cost of living, a suitable proxy for income, as well as information on whether respondents live in urban, suburban, or rural areas.
I have also consulted data from the China Statistical Yearbook series, published annually by the Chinese National Bureau of Statistics. The Statistical Yearbooks contain more general statistics, including population growth and sex composition at the national and provincial levels.
Unfortunately, the yearbooks contain no information about the birth population, diminishing their usefulness for the purposes of this paper.
Finally, I have consulted annual reports on the Chinese National Bureau of Statistics websites curated by government agencies, and data from the World Bank and the United Nations in my efforts to find some of the figures for China’s sex ratio at birth since 1990. Given the

sensitive nature of these statistics, I have had to gather these them from a variety of sources,
since no authoritative set of figures was available.
IV. Models of Sex-selection
In order to form a working hypothesis about the effect of education on China’s sex ratio at
birth, I will first delineate a set of theoretical frameworks in which to conceptualize the effect of education on fertility decisions. My analysis of the mechanics of fertility decision-making draws
heavily on two models of sex preference. One (Echavarri and Ezcurra, 2010) attempts to explain
the relationship between individual educational attainment, the reproduction of cultural beliefs
and values across generations, and sex-selective behavior. The other (Ebenstein, 2010) presents
the relationship between the legal framework of the One Child Policy, with its many local
variants, and the series of information sets presented to prospective parents in China.
Echavarri and Ezcurra (2010) present a general model of the effect of education on sex-
selective behavior in India. While the demographic policy environments in India and China are
not perfectly analogous, these two countries share a widespread cultural preference for sons, as
well as economic factors that motivate biases in favor of male offspring. Since male earning power is relatively high in both China and India, parents may favor sons as a result of economic necessity or social security. This is especially true in China, where the state provides little social
security, leaving children in charge of care for their aging parents. Echavarri and Ezcurra’s model
is defined as follows.
Consider a population where (for the sake of simplicity) each generation is composed of n individuals. Of these n individuals, exhibit son preference, where 0 1. Thus, some fraction of the population will, given access to the technology required for sex-selection, seek an 12
abortion should they discover that they have conceived a female child. In the absence of any
external influence (education, for instance) children in one generation acquire their parents’
beliefs, and therefore, without such influence, individuals in one generation will display
preferences identical to those of their parents in the previous generation.
Let , where 0 1, represent the share of the population with access to the
technology required to determine the sex of an unborn child and subsequently to seek an
abortion. In spite of the prevalence of sex-selection in China and India, some people may not be
able to afford the tests and procedures that are required for sex-selection, and while the number
of counties where ultrasound technology is readily available has risen steadily over the past 30
years (Chen, Li, and Meng, 2013), government policy measures designed to combat sex-selection
have increased the expense and difficulty associated with sex-selective abortion (Kristof, 1993).
Furthermore, ultrasound was adopted in a piece-wise manner throughout China, with some
provinces not gaining ultrasound-equipped facilities until the 1990s (Chen et al.: 2013). It
therefore makes sense to assume imperfect access to ultrasound technology in China, as in India.
The model incorporates education in the form of an exogenous shock where the
population is divided into a group of individuals who are educated and individuals who are not. Some portion of the educated group, where 0 1, exhibits son preference (as
defined above) and some portion of the educated group has access to sex-selective technology.
By merit of increased income and mobility associated with higher levels of education, we may assume that , however, as we will soon see, the relationship between and is uncertain.
The individuals who are unaffected by the aforementioned educational shock retain the
characteristics of the population before the shock. That is, of these individuals have access 13
to sex-selective technology (by merit of income and proximity), and of these individuals exhibit son preference.
In order to fully conceptualize the effect of the educational shock on the realization of sex- preference (through sex-selective abortion) within the population following the shock, we
